Definitions

  • the present invention relates to an assembly comprising a valve and a protective cap and a bottle comprising such an assembly.
  • the invention more particularly relates to an assembly comprising a valve for controlling a fluid under pressure and a protective cap mounted around said valve, as defined by claim 1.
  • the invention relates in particular to a system for delivering gas from a bottle, in particular a bottle of small volume (10 liters of geometric volume containing compressed gas at, for example, 150 to 300 bar).
  • the invention applies in particular to bottles equipped with a valve easily connectable to regulators of different types and ensuring (the valve) an emergency stop function (or at least a quick stop) of the withdrawal of the gas and giving a visible indication on the "open” (On) or “off” (Off) state of the faucet.
  • valve is described for example in documents FR-A1-2828922 or FR-A1-2793297 (The invention can be applied to any other type of valve and is not limited to the examples described in the documents above).
  • the invention therefore also relates to a protective cap, preferably of composite material, having an opening for handling a valve actuating lever, however the cap is sufficiently covering to protect the valve in case of a fall for example.
  • a valve having at least one lever likely to overflow out of the protection volume conferred by the cap has better visibility and better maneuverability for an operator.
  • the document EP 747 796 describes such an assembly in which the cap is mounted on the bottle in a fixed indexed angular position and determined with respect to the valve.
  • a rotating cap relative to the faucet and the bottle, to provide the user with some freedom to facilitate installation, maintenance and connection to the faucet.
  • a rotating cap In use position a rotating cap is mounted "crazy" that is to say free to rotate relative to the entire valve and bottle. That is to say that the user can choose (turn) the angular position of the cap without having to disassemble it (the locking in translation is however preserved).
  • a rotating cap is particularly advantageous when installing the valve on the bottle because it does not require angular indexing between the valve and the cap. Being able to orient the cap (rotating) relative to the fixed valve also increases the convenience of use, for example to connect a regulator or a hose. Finally, to check the condition of the valve and / or to maintain it, the fact of being able to turn the cap makes it possible to examine the valve and its connection to the bottle from all angles and makes it possible to intervene easily.
  • An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
  • the assembly according to the invention is essentially characterized in that the cap is rotatable relative to the valve body around the vertical axis and in that the portion of the cap defining the first opening has contact edges likely to come into contact with the lever when on the one hand it intercepts the plane of the first opening and on the other hand the cap is rotated relative to the valve, the contact edges being oriented at predetermined angles to induce a force on the lever urging it to its first position.
  • the invention may also relate to a bottle of pressurized fluid, in particular nitrogen-containing gas, the assembly being mounted at its orifice, the valve being rotatably mounted on the bottle, for example by screwing, and in that the cap is rotatably mounted relative to the vertical axis of the bottle and the valve via a rotating fastening system such as a circlip cooperating with a groove.
  • a bottle of pressurized fluid in particular nitrogen-containing gas
  • the invention may also relate to any alternative device or method comprising any combination of the above or below features.
  • the device illustrated in figure 1 comprises a pressurized gas bottle 3 in the orifice of which is mounted (for example by screwing) a valve 1 provided with a pivoting lever 5 (for actuating a valve or isolating valve for example).
  • the lever 5 is for example articulated in the upper part of the valve 1 and can be moved manually between a position near the valve body 1 on a side face of the valve (valve closed) and a position separated by a non-zero angle (open valve ).
  • the lever 5 may include other intermediate positions (open or closed valve).
  • valve 1 On another of its side faces the valve 1 may comprise a pressure gauge 14 (or outlet can receive such a gauge) and a take 4 draw (intended to be connected to a hose for example).
  • a pressure gauge 14 or outlet can receive such a gauge
  • a take 4 draw intended to be connected to a hose for example.
  • a cap 2 is mounted around the valve 1 in a rotating manner. That is to say that the cap 2 is linked in translation to the bottle 3 but can rotate relative to the bottle about the vertical axis A of the bottle 3 and the valve 1. Preferably, the cap 2 can rotate freely 360 ° around the tap 1.
  • Hat 2 may comprise a structure forming two substantially vertical "arches” (or lobes) formed on two lateral flanks of hat 2.
  • a first arch defines a first lateral opening 12 intended to be disposed opposite the lever 5.
  • the second arch defines a second 22 and a third 32 lateral openings.
  • the lever 5 When the lever 5 is located vis-à-vis the first opening 12, the pivoting of the lever 5 outwards is possible between two extreme positions. In its spaced apart position the lever 5 intersects the imaginary plane of the first opening 12 and may project beyond the volume of the cap 2 (cf. figures 1 and 3 ).
  • these contact edges 102 are oriented at predetermined angles to induce in this case a force on the lever 5 urging it towards its folded position (towards the valve body 1).
  • the contact edges 102 may have an inclined orientation B with respect to the vertical axis A and / or at least a portion of the contact edges 102 are bent or inclined towards the interior of the first opening and / or the contact edges 102 have a portion inclined at an angle of between 14 and 30 degrees and preferably between 17 and 25 degrees with respect to the vertical axis A.
  • the inclined portion may be included in a curve such as a segment of a circle.
  • the tangent to the curve makes with the vertical axis, an angle at least equal to the minimum of the limits described above.
  • the second opening 22 and the third opening 32 are arranged one 22 above the other 32 and separated by the horizontal post 52 which can form a gripping member of the bottle 3.
  • the dimensions of the second 22 and third 32 openings are preferably selected so as to prevent lever 5 from pivoting thereon.
  • the dimensions of the second 22 and third 32 openings are also provided to make it impossible (or poorly) to mount a regulator on the filling plug 4 when the latter is located vis-à-vis the second arch.
  • the cap 2 further comprises a fourth opening 42 located on a side face between two adjacent ends of the two arches.
  • the fourth opening 42 (preferably open at the top) is provided to form a sufficient access to the face of the valve 1 provided with the gauge 14 and the take 4 draw (for mounting a pressure regulator) and optionally d a filling plug (not shown).
  • the cap 2 is shaped to allow the use of the valve of the bottle 3 only in a finite sector of angular positions of the cap 2 with respect to the tap 1. In the rest of the angular positions, the cap 2 can be dimensioned either to prevent the complete pivoting of the lever 5, or to prevent the connection of a regulator (or other organ) to the socket racking 4.
  • the cap 2 is shaped to prevent the correct use of the valve 1 in these positions (ie the lever 5 can not be properly lifted or a regulator can not be connected).
  • the cap 2 is made of plastic and has a relative elasticity during an impact.
  • the cap 2 also has a light structure to protect the valve 1 without using a large amount of material (weight and cost).
  • This very aerated architecture also ensures good visibility of the interior of the protected volume.
  • the invention applies in particular to multi-purpose portable gas cylinders (itinerant professional applications in particular) for which the valve built-in trigger is not necessarily provided because of, for example, too great a pressure adjustment dynamic or in flow or because of requirements that vary from one use to another (request for control of flow rate or pressure).
  • the invention can be applied to nitrogen cylinders for air conditioning system installers for whom, depending on whether to inert pipes or fill a circuit or leak test, and according to the types of systems, the required pressure can vary between 1 bar and 50 bar.
  • the invention can also be applied to cylinders used on a high-pressure circuit (central, backup power supply, safety devices) without regulator directly connected.
  • the invention can however also be applied to valves with integrated expansion valve.
  • the invention may where appropriate relate to all or part of the technical characteristics of the cap independently of the valve.
  • the technical characteristics of the cap 2 can be realized by giving the cap 2 other shapes / arrangements, it being understood that, in all cases (including the example shown), the characteristics of the invention are independent of the aesthetic appearance of the hat.
